Abstract: A secondary ion mass spectrometer comprises: (a) a first primary ion source for generating a first pulsed primary ion beam with short pulse durations; (b) a second primary ion source for generating a second pulsed primary ion beam with pulse durations in the range of 50 ns and up to 5 s; (c) a first TOF-SIMS analysis unit for mass spectroscopic analysis of the secondary ions generated by the primary ion pulses of the first primary ion source from a sample; and (d) a second analysis unit for mass spectroscopic analysis of the secondary ions generated by the primary ion pulses of the second primary ion source from a sample.

Abstract: Diving equipment includes a compressed air bottle connected to a breathing apparatus and an inflatable jacket via which buoyancy is balanced by the jacket being connected to the compressed air bottle to be inflated or to an outlet to be deflated. A monitoring device is activated via a control valve as a function of surrounding water pressure and has a time monitoring unit which, after the expiry of a defined time and in the absence of breathing activity in the breathing apparatus, changes to emergency operation and activates an emergency valve via a control line connecting the jacket to the compressed air bottle to force inflation of the jacket. Actuation of at least one regulating valve is influenced during a dive by the monitoring device and/or the control valve. In manual activation, the jacket is inflated via the inflation valve, and the compressed air is bled via the outlet valve.

Abstract: Described is a method for analysis of a solid sample and, in particular, for analysis of the material composition and distribution in or on a solid surface. The surface to be analysed is covered with caesium, at least partially and/or in regions, and the surface is irradiated with an analysis beam which contains predominantly or exclusively polyatomic ions with at least 3 atoms per ion. The secondary ions which are produced are then analysed on caesium compound.

Abstract: A device (10), which is for holding a transport unit (W) that moves in a transport direction (T), includes an actuator (16) equipped with a drive unit (16c/16d) and an actuating element (16a), which, in an extended position, can be brought directly or indirectly into a holding engagement with the transport unit (W); a sensor unit (22) that is situated before the actuator (16) and a sensor unit (24) that is situated after the actuator (16), both of which are for detecting the presence of a transport unit (W); and a control unit (28) for receiving the detection results of the transport unit sensor units (22, 24) and controlling the actuator (16), wherein the two sensor units (22, 24), the control unit (28), and at least the drive unit (16c/16d) of the actuator (16) are integrated into a shared housing (12).

Abstract: A pressure cylinder including a cylinder housing having one end including an opening. A piston is axially displaceable within the cylinder housing. A piston rod is coupled to the piston and extends through the opening at the one end of the cylinder. A cylinder base closes off the cylinder at an end of the cylinder housing opposite the opening. The cylinder also includes a pressure chamber between the piston and the cylinder base and capable of being pressurized by a pressure medium and a switching disk for interacting with a switch to determine the position of the piston. The switching disk is displaceably positioned in the pressure chamber in frictional engagement and coaxially with the piston rod so that the switching disk passes to a starting position near the piston in response to a pressure impulse overcoming the frictional engagement when the pressure chamber is first pressurized.

Abstract: A double pressure cylinder arrangement including a first pressure cylinder and a second pressure cylinder positioned in a spaced and axis-parallel relationship to the first pressure cylinder. A carrier strut is connected to a bottom side of the first pressure cylinder and the second pressure cylinder. The carrier strut includes a intermediate section. A substantially u-shaped housing element has two leg sections. Each leg section houses one of the pressure cylinders. Connection lines for driving the first pressure cylinder and the second pressure cylinder are integrated in the intermediate section.

Abstract: A plug-in connector, especially for hose connections and for use in motor vehicles, including a receptacle and a plug. The receptacle may be provided with an insertion opening for receiving the plug and a groove for retaining at least one locking spring which may be used to lock the receptacle and plug together. The locking spring may include at least one locking section and one unlocking section which can be actuated from the outside of the receptacle. The receptacle may also include an unlocking opening accessible from outside of the receptacle and which discharges into the groove so that the unlocking section of the unlocking spring may extends from the groove into the unlocking opening. The locking spring is retained in the groove in a manner that the locking section is moved outward in a substantially radial direction into the groove when a force is applied to the unlocking section, thus disengaging the locking section from the plug and allowing separation of the plug and the receptacle.
